Abstract
3D numerical simulation was conducted for an axial two-stage transonic fan with partspan shroud under subsonic condition. The calculated overall and blade element performance lines showed good agreement with the experiments, so detailed flow field analysis was carried out. It was found that the low-energy zone due to separation of boundary layer of the first stage's rotor tip and the blocking it caused were the factors leading to flow instability under subsonic condition.
